European nations have gone to war more than once to preserve their unique national identities. Now, because of the liberal madness of “multiculturalism”, they have allowed and in some cases invited people who are from outside cultures and outside religions to immigrate.
Where these immigrants have been Muslim, many have not had any intention on assimilating. So they have tended to form enclaves, sometimes enabled by government welfare policies.
Worse, the more conservative Muslims not only have no intention of assimilating, but because they have substantially higher birth rates than the indigenous peoples, they intend to take over their host country some day. They have no intention on preserving the culture of their hosts.
In short, in the pursuit of a liberal Utopia, these host countries have commenced a cultural self-destruction sequence that will end in a Sharia-observing Islamic state. And descendants of the indigenous hosts who remain in a few generations will be forced into subservient dhimmihood status.
I have long suspected that the locals must wake up and either suppress the Muslim immigrant groups or eject them entirely. Somebody is going to get hurt either way, either now or in one or two more generations, and nit is not going to be pretty. This debacle is a ticking time bond.
Some European countries have ‘guest worker’ programs such as are being proposed here. These guarantee an unassimilatable population hostile to the native culture.
